DEMI RESSORT A TENSION REGLABLE UTILISE
POUR LA REALISATION DE COUTEAU
La présente invention est relative à la conception d'un type de couteau fermant, reposant sur la création d'un demi ressort à talon qui, par sa surface d'appui sur la matière du manche, permet d'obtenir une flexibilité nécessaire à la fermeture et l'ouverture de la lame.HALF SPRING WITH ADJUSTABLE TENSION USED
FOR THE REALIZATION OF KNIFE
The present invention relates to the design of a type of closing knife, based on the creation of a half heel spring which, by its bearing surface on the material of the handle, makes it possible to obtain a flexibility necessary for the closing and opening of the blade.
Dans l'état de la technique antérieure, les ressorts de fermeture étaient montés avec plusieurs points d'ancrage. Aucun réglage de tension du ressort n'était prévu. In the state of the prior art, the closing springs were mounted with several anchoring points. No spring tension adjustment was planned.
La présente invention définit la longueur du talon du demi ressort en fonction de la nature de la matière constituante du manche. Les matières prévues dans le présent brevet sont différentes essences de bois précieux et d'aluminium anodisé mais le choix peut s'étendre à toutes matières utilisables, plastique, alliages, matériaux composites, minéraux et divers. The present invention defines the length of the heel of the half spring as a function of the nature of the constituent material of the handle. The materials provided for in this patent are different species of precious wood and anodized aluminum, but the choice may extend to all usable materials, plastic, alloys, composite materials, minerals and various.
Le réglage de la tension du demi ressort est obtenu par une vis. The tension of the half spring is adjusted by a screw.
La course de réglage (filetage) est très faible et obtenue par un simple tournevis adapté. Ainsi, la force de fermeture peut être définie à la convenance de l'utilisateur.The adjustment stroke (thread) is very small and obtained by a simple suitable screwdriver. Thus, the closing force can be defined at the convenience of the user.
Le vissage de réglage est toutefois limité en course pour ne pas atteindre la rupture du demi ressort. The adjustment screwing is however limited in stroke so as not to reach the rupture of the half-spring.
DESCRIPTION
Le type de couteau fermant est composé d'un demi ressort à talon figure 1 (1) ayant un seul point d'ancrage (2) avec le manche monobloc ou non constitué d'une vis (3) et d'une douille à vis figure 2 (4). La longueur du talon figure 1 (s) sur la matière constituant le manche détermine la flexibilité du demi ressort dans sa partie médiane nécessaire lors de l'ouverture et de Ia fermeture de la lame. La longueur du talon est définie en fonction de la nature de la matière du manche (aluminium anodisé ou divers bois par exemple).DESCRIPTION
The type of closing knife is composed of a half heel spring in figure 1 (1) having a single anchor point (2) with the monobloc handle or not consisting of a screw (3) and a screw socket. Figure 2 (4). The length of the heel Figure 1 (s) on the material constituting the handle determines the flexibility of the half-spring in its median part necessary during the opening and closing of the blade. The length of the heel is defined according to the nature of the material of the handle (anodized aluminum or various woods for example).
Une vis de réglage figure 1 (6) positionnée dans le manche par une douille taraudée permet par simple vissage ou dévissage avec un tournevis d'obtenir la tension réglage de fermeture et d'ouverture de la lame souhaitée par l'utilisateur. Toutefois, la course de réglage est limitée pour éviter toute possibilité de rupture du demi ressort. An adjustment screw in Figure 1 (6) positioned in the handle by a threaded socket allows by simple screwing or unscrewing with a screwdriver to obtain the adjustment voltage for closing and opening the blade desired by the user. However, the adjustment stroke is limited to avoid any possibility of the half-spring breaking.
Le demi ressort ainsi positionné permet l'ouverture et la fermeture de la lame figure 1 (7) par rotation autour de l'axe (8) constitué selon le même principe d'assemblage que le point d'ancrage du ressort par vis (3) et douille à vis figure 2 (4). The half spring thus positioned allows the opening and closing of the blade in Figure 1 (7) by rotation about the axis (8) formed according to the same principle of assembly as the anchor point of the spring by screw (3 ) and screw socket figure 2 (4).
L'ouverture se fait par système du cran forcé connue dans les règles de l'art de la coutellerie. The opening is done by forced notch system known in the rules of the art of cutlery.
La conception d'assemblage par vissage et notamment au niveau de l'axe figure 1 (8) de la lame a été déterminée pour effectuer le réglage au minimum du jeu de la lame par rapport au manche qui peut se créer en fonction de l'usage. The assembly design by screwing and in particular at the level of the axis of FIG. 1 (8) of the blade was determined in order to make the adjustment to the minimum of the clearance of the blade relative to the handle which can be created according to the use.
Par ailleurs, cette conception permet l'interchangeabilité de la lame par l'utilisateur lui-même. Furthermore, this design allows the interchangeability of the blade by the user himself.
La mouche de ressort figure 2 (9) aura pour fonction de limiter la course du ressort et de faciliter l'opération de montage du couteau. La mouche de ressort sera conçue d'aspect différent selon les modèles affirmant l'image du produit en association avec la forme extrême du manche. The function of the spring fly in FIG. 2 (9) will be to limit the stroke of the spring and to facilitate the operation of mounting the knife. The spring fly will be designed in a different aspect depending on the models asserting the image of the product in association with the extreme shape of the handle.
Le manche figure 2 (10) monobloc dans la description du produit, mais pouvant être constitué de plusieurs parties dans les variantes de l'invention, sera constitué de matières dites nobles ou présentant un intérêt esthétique. Le manche est composé d'une partie ergonomique, partie entre la lame et les 2/3 du manche figure 3 (12). La zone (11) est adaptée à la position du pouce lors de l'opération de fermeture de la lame ou de l'index lors de l'opération de coupe. La partie centrale (12) du manche est conçue pour une prise en main confortable et efficace. The handle in FIG. 2 (10) in one piece in the description of the product, but which may consist of several parts in the variants of the invention, will be made of so-called noble materials or of aesthetic interest. The handle is made up of an ergonomic part, part between the blade and 2/3 of the handle in figure 3 (12). The zone (11) is adapted to the position of the thumb during the closing operation of the blade or the index finger during the cutting operation. The central part (12) of the handle is designed for a comfortable and effective grip.
Par ailleurs, la partie du manche opposée à la lame a une fonction décorative en cohérence avec la mouche de ressort et détermine avec celle-ci l'identification du modèle et parfait son image. Furthermore, the part of the handle opposite the blade has a decorative function in coherence with the spring fly and determines with it the identification of the model and perfects its image.
La partie ergonomique assure donc le confort de la prise en main ainsi que la sécurité car empêche le dérapage de la main pendant la coupe et conforte la sécurité à la fermeture. The ergonomic part therefore ensures comfort in the hand as well as safety because it prevents the hand from slipping during the cut and improves safety when closing.
Le principe de l'invention est susceptible de développement industriel car il génère la possibilité de production de couteaux de modèles différents, monoblocs ou non, présentant un intérêt ergonomique, esthétique et, de plus, la conception de l'invention apporte des possibilités de réglage et d'interchangeabilité par l'utilisateur lui-même. The principle of the invention is susceptible of industrial development because it generates the possibility of producing knives of different models, monobloc or not, having an ergonomic, aesthetic interest and, moreover, the design of the invention provides adjustment possibilities. and interchangeability by the user himself.
